Architecture

The app is using MVVM architecture, the main goal is to mantain everything under a simple but effective MVVM implementation.

• Modules

  Each Module has ViewModel, Models, Views to handle the base Architecture design.

• ViewModels

  ViewModel is the main component of this architecture pattern. ViewModel never knows what the view is or what the view does. This makes this architecture more testable and removes complexity from the view. The ViewModel invokes changes in the Model and updates itself with the updated Model, and since we have a binding between the View and the ViewModel, the first is updated accordingly.

• Models

  Model refers either to a domain model, which represents simple data.

• Network Layer

  Network layer is a set of Services Protocols to handle the API calls to the Endpoints using an Adapter and Protocol Oriented programming.

Please consider this article if it is your first time using MVVM: https://medium.com/@azamsharp/mvvm-in-ios-from-net-perspective-580eb7f4f129

Frameworks

The app is using some external frameworks dependencies using Cocoapods:

• Alamofire

  • A network layer to handle REST API requests for HTTP request, used to implement the Service Network API calls.

• SDWebImage

  • A framework to handle image URL downloads easy and quick to download and display the Movie Posters

• SwiftLint

  • A framework to handle best practices lint rules for Swift used as a best practice
